I cleaned up and made some progress, and now the first network card works: a
Corega ethernet PCMCIA supported by pcnet_cs - the same card is already
supported in the apne driver, though with the PCMCIA bridge, you get hot
plugging too.

Unfortunately, other PCMCIA cards I tested still don't work (an Etherlink
ethernet card, a CF adapter, a Ratoc serial card, and an 802.11 wifi card - all
of them with varying degrees of "not working").

I should probably repost the cleaned up driver.
